Solid-state electrolyte CO2 Module FS00306​ Introduction

FS00306 is a sensor used to monitor carbon dioxide concentrations. Based on the principle of solid electrolyte, it fundamentally solves the problem of infrared carbon dioxide sensors being easily affected by water vapor interference, and has characteristics such as high stability and strong environmental adaptability. It is particularly suitable for special environments such as agricultural greenhouses, breeding ponds, tunnels, and mines.
